SAMUEL P. FRALEY, OF CHICAGO, ILLINOIS.

BROOM-BINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 757,103, dated April 12, 1904. Application filed May 22, 1903. Serial No. 158,272. (No modelJ To all whom it may concern.-

Be it known that I, SAMUEL P. FRALEY, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a new and useful Improvement in Broom-Binding Machines, of which the following is a specification.

The object of my invention is the construction of a machine which shall securely bind broom-blanks into the desired shape and, further, to effect this in such manner as to prevent future shrinkage or loosening of the straw and prolong the life of the broom,while adapting the machine to the manufacture of brooms of different widths and sizes. I accomplish this result by subjecting the blank (or shapeless bunch of straw secured at one end to a handle) to a heavypressure between the dies of the desired shape, each carrying bands or wires in position for binding, and by bending and clenching the ends of these wires into the straw before removing the pressure in such manner as to press the straw between them and to loop their ends around on either side and turn them into the straw, so that they will maintain the compression and will not spring or pull off in ordinary use after pressure is removed or expose the ends.

In the accompanying drawings, wherein like letters and numbers d enote like parts throughout the several figures, I have shown a machine embodying the preferred form of my invention.

Figure 1 is an elevation of the feed side of my machine, and Fig. 2 is an end elevation. Fig. 3 is a plan section on line 3 of Fig. 1 in the direction of the arrow, showing the parts in initial position ready to receive a broomblank. Fig. 4 is a similar view showing the parts in the second position with the wirebenders moved forward to grasp the bindingwires. Fig. 5 is a similar view showing the parts in the third position, the clenchers moved into engagement with the wires, and the benders left idle in the rear of the revolving carriers or heads. Fig. 6 is asimilar view of the parts in the fourth or final position, showing the plunger forced into the revolving heads and the clenchers in the final act of seating 5 and locking the wires in the broom. Fig. 7

is an enlarged fragmentary view of one of the revolving heads. Fig. 8 is a view, partly in section and partly in elevation, of one of the revolving heads looking in the direction of the wire-benders. Fig. 9 is a similar view of the same head after it is turned over to bring the clenchers into view. Fig. 10 is a transverse section of the head on line 10 of Fig. 7 looking in the direction of the arrow. Fig. 11 is a similar section of the same, showing the plunger for forcing the clencher-jaws together in the act of clenching the wires. Fig. 12 is a detail perspective of the end of one of the revolving heads, showing the cam-gate in its initial position. Fig. 13 is a similar view in an advanced position. Fig. 14 is a similar view showing the parts in their return movement during the revolution of the head. Fig. 15 is an end elevation of, a revolving head. Fig. 16 is a detail sectional view of a revolving head on line 16 of Fig. 7 Fig. 17 is a similar view on line 17 of Fig. 7. Fig. 18 is a detail sec tion on line 18 of Fig. 15 of the spring-finger device around which the wire ends are curved and which automatically releases the wires on the return movement of the revolving heads. Fig. 19 is a detail section on line 19 of Fig. 7 of a revolving head, showing the clencher-jaws opened. Fig. 20 is a similar view showing the clencher-jaws compressed or closed. Fig. 21- is a detail section of a re' volving head on line 21 of Fig. 10, showing the spring-pin. Fig. 22 is a face view of the pinion on the end of the revolving head, showing the cam-locking grooves. Fig. 23 is an end view of one of the heads with the pinion,

of the upper die, and Fig. 27 a top view of the lower die. Fig. 28 is a section on line 28 of Fig. 26, showing the construction of one of the catches for holding the upper wires in place. Fig. 29 is a sectional view on line 29 of Fig. 27 showing the slots in the die for the
